Flights have resumed in the United States after a major disruption that halted operations at airports across the country. During the restrictions, almost 5,000 flights were canceled, and more than 10,000 were delayed.

According to Transport Minister Sean Duffy, the cause may have been overloading of outdated traffic control equipment. Authorities found no signs of a cyber attack.

Duffy is now demanding $50 billion to modernize the airport infrastructure.
